5.5 Parameter: Group 3 Service Parameter
Mode 1 Code number
Value: 3
Mode 2 DC rest voltage of the sensor
The DC rest voltage of the sensor is displayed. This should be in case of
sensors
•
type AS–02x between -14 V DC and -10 V DC
•
Typ AS-06x bei 12,5 V ± 1,5V supply powered sensors
•
type AS-06x (CCS) 13 V DC ± 1,5 V constant-current powered sensors
•
type VS-080 0,8 V DC
With more negative voltages the display will flash.
Mode 3 Internal voltage 5 Volt
The 5 Volt power for the internal components of the instrument is displayed.
The value should be in the range 4.8 V to 5.2 V. Values outside this range
lead to the error message ' 02'.
Mode 4 Internal voltage 17 Volt
The 17 Volt power for the internal components of the instrument is displayed.
The value should be in the range 16.8 V to 19.0 V. Voltage values outside
this range will lead to the error message ' 02'.
Mode 5 Housing internal temperature
The temperature inside the instrument housing is displayed in °C. If the
temperature inside the instrument exceeds the predefined limit the error
message ' 03' will be displayed.
Mode 6 Input amplifier amplification factor
The current amplification factor of the input amplifier is displayed in steps of
1 - 2 - 4 - 8 - ... 128.
Mode 7 Output of the D/A converter
The display range of 0 ... 127 corresponds to 0 ... 20 mA
